Embodiment 1

[0041] figure 2 It is a schematic flowchart of an inter-satellite service transmission method provided in Embodiment 1 of the present application. The method includes the following steps:

[0042] S101. Receive a service packet to be transmitted;

[0043] S102. If there is a destination satellite in the service package, determine the shortest path to the destination satellite, and transmit the service package to the next node on the shortest path until reaching the destination satellite;

[0044] S103. If there is no destination satellite in the service package, determine the shortest path among the paths to all the first satellites currently connected to the earth station, and package the first satellite corresponding to the shortest path as the destination satellite into the service packet, and transmit the service packet to the next node on the shortest path until reaching the destination satellite.

[0045] As an example, the executor of this embodiment may be an inter-...

Abstract

The invention provides an inter-satellite service transmission method and device, electronic equipment, a medium and a product. The method comprises the following steps: receiving a to-be-transmitted service packet; and if a target satellite exists in the service packet, determining a shortest path to the target satellite, and transmitting the service packet to a next node of the shortest path until the service packet reaches the target satellite. And if no target satellite exists in the service packet, determining the shortest path in the paths of all first satellites currently accessed to the earth station, packaging the first satellite corresponding to the shortest path into the service packet as the target satellite, and transmitting the service packet to the next node of the shortest path, and the target satellite is reached. According to the scheme, addressing is independently carried out on each satellite of the constellation to transmit services, and dynamic routing selection can be achieved without complex operation.

Description

technical field [0001] The present application relates to the field of satellite communication, in particular to an inter-satellite service transmission method, device, electronic equipment, medium and product. Background technique [0002] The low-orbit IoT constellation system has the characteristics of wide coverage, real-time communication, and low power consumption. It can effectively supplement the coverage blind spots of the ground communication network, and effectively improve the data transmission problems in sea and air network blind spots. At present, the low-orbit IoT constellation is widely used in emergency communication and rescue, environmental protection monitoring, meteorological monitoring, transportation of dangerous chemicals, aircraft tracking and monitoring, earthquake monitoring and forecasting, smart cities, smart oceans, smart agriculture, oil and gas pipeline networks, and power pipeline networks Monitoring and wildlife protection and other fields....
